==================================================================
对于使用托盘图标的程序,当我们通过强制结束进程,或者程序异常退出时,托盘图标区域总会有托盘图标的残留,需要我们用鼠标移到残留区域时,托盘图标才会自动消失。有时我们需要去做相关的处理,比如在软件升级时,会强制结束进程,这时需要自动的去清除残留的托盘图标。通过研究和查阅网络,整理如下的方法。
1、实际上托盘图标区域对应一个ToolbarWindow32工具条窗口,每个托盘图标对应一个按钮,通过遍历找到指定程序的按钮ID,向这个按钮ID发送TB_HIDEBUTTON,使托盘图标消失,代码如下:
[cpp] view plain copy
- HWND hWnd,hWndPaper;
- unsigned long lngPID;
- long ret,lngButtons;
- HANDLE hProcess;
- LPVOID lngAddress;
- long lngTextAdr,lngHwndAdr,lngHwnd,lngButtonID;
- char strBuff[1024]={0};
- char* str = NULL;
- char *pp = NULL;
- hWnd = ::FindWindow( "Shell_TrayWnd", NULL );
- hWnd = ::FindWindowEx( hWnd, 0, "TrayNotifyWnd", NULL );
- hWndPaper = ::FindWindowEx( hWnd, 0, "SysPager", NULL );
- if( !hWndPaper )
- hWnd = ::FindWindowEx( hWnd, 0, "ToolbarWindow32", NULL );
- else
- hWnd = ::FindWindowEx( hWndPaper, 0, "ToolbarWindow32", NULL );
- ret = GetWindowThreadProcessId( hWnd, &lngPID );
- hProcess = OpenProcess( PROCESS_ALL_ACCESS
- |PROCESS_VM_OPERATION
- |PROCESS_VM_READ
- |PROCESS_VM_WRITE,
- 0,
- lngPID );
- lngAddress = VirtualAllocEx( hProcess,0, 0x4096, MEM_COMMIT, PAGE_READWRITE );
- lngButtons = ::SendMessage( hWnd, TB_BUTTONCOUNT, 0, 0 );
- for( int i=0; i< lngButtons - 1; i++ )
- {
- ret = ::SendMessage( hWnd, TB_GETBUTTON, i, long(lngAddress) );
- ret = ReadProcessMemory( hProcess, LPVOID(long(lngAddress) + 16), &lngTextAdr, 4, 0 );
- if( lngTextAdr != -1 )
- {
- ret = ReadProcessMemory( hProcess, LPVOID(lngTextAdr), strBuff, 1024, 0 );
- ret = ReadProcessMemory( hProcess, LPVOID(long(lngAddress) + 12), &lngHwndAdr, 4, 0 );
- ret = ReadProcessMemory( hProcess, LPVOID(lngHwndAdr),&lngHwnd, 4, 0 );
- ret = ReadProcessMemory( hProcess, LPVOID(long(lngAddress) + 4), &lngButtonID, 4, 0 );
- USES_CONVERSION;
- str = OLE2T( (LPOLESTR)( strBuff ) );
- pp=strstr( str,"阿里旺旺" ); // 通过窗口名称来比对
- if(pp != NULL)
- {
- ::SendMessage( hWnd, TB_HIDEBUTTON, lngButtonID, 1 );
- }
- }
- }
- VirtualFreeEx( hProcess, lngAddress, 0X4096, MEM_RELEASE );
- CloseHandle( hProcess );
上述方法比较负责,但相对合理很多,但是这种方法只对win2000,XP系统有效,对与Win7却无能为力,没有效果。
3、对于Win7系统,程序的托盘图标最终是放置在和XP一样的ToolbarWindow32工具条窗口,但是有两个地方,同样是ToolbarWindow32工具条窗口,父窗口是不一样的。在右下角可见区域,ToolbarWindow32工具条窗口的父窗口是SysPager窗口,遍历方法同XP一样。对于掩藏的ToolbarWindow32工具条窗口,必须通过点击桌面右下角的可见区域左边的一个按钮,才会显示出来,其父窗口则是一个叫做托盘溢出的窗口NotifyIconOverflowWindow。所以除了这两个地方都要查找,查找后面的ToolbarWindow32工具条窗口,则只要直接查找NotifyIconOverflowWindow即可,代码如下:
[cpp] view plain copy
- //获取托盘溢出区域窗口句柄
- hWnd = ::FindWindow(_T("NotifyIconOverflowWindow"), NULL);
- hWnd = ::FindWindowEx(hWnd, NULL, _T("ToolbarWindow32"), NULL);
上述相关代码已通过实际测试,均能达到指定的效果。
================================================================
方法二:(已测试,在XP下可用)
//--------找出该图标所对应的进程ID,如果该ID为NULL则删除该图标--------//
bool refreshTray()
{
HWND hStatus=::FindWindow("Shell_TrayWnd",NULL); //得到任务栏句柄
if (hStatus==NULL)
{
qDebug()<<"Get Shell_TrayWnd error!\n";
return false;
}
HWND hNotify=FindWindowEx(hStatus,NULL,"TrayNotifyWnd",NULL); //右下角区域
if (hNotify==NULL)
{
qDebug()<<"Get TrayNotifyWnd error!\n";
return false;
}
HWND hNotify1=FindWindowEx(hNotify,NULL,"SysPager",NULL);
if (hNotify==NULL)
{
qDebug()<<"Get SysPager error!\n";
return false;
}
HWND hNotify1_0=FindWindowEx(hNotify1,NULL,"ToolBarWindow32",NULL);//右下角区域(不包括时间)
if (hNotify1_0==NULL)
{
qDebug()<<"Get ToolBarWindow64 error!\n";
return false;
}
//-------------------以上是得到任务栏右下脚一块地方的句柄-----------------//
DWORD pid = 0;
GetWindowThreadProcessId(hNotify1_0,&pid);
if (pid==NULL)
{
qDebug()<<"Get pid error!\n";
return false;
}
HANDLE hProcess=OpenProcess(PROCESS_QUERY_INFORMATION|PROCESS_ALL_ACCESS,true,pid);
if (hProcess==NULL)
{
qDebug()<<"Get hd error!\n";
return false;
}
::SendMessage(hNotify1_0,WM_PAINT ,NULL,NULL);
CRect rect;
::GetWindowRect(hNotify1_0,&rect);
::InvalidateRect(hNotify1_0,&rect,false);
int iNum=::SendMessage(hNotify1_0,TB_BUTTONCOUNT ,NULL,NULL); //获取任务栏上图标个数
unsigned long n = 0;
TBBUTTON *pButton = new TBBUTTON;
CString strInfo = _T("");
wchar_t name[256] = {0};
TBBUTTON BButton;
unsigned long whd,proid;
CString x;
for(int i=0; i<iNum; i++)
{
::SendMessage(hNotify1_0,TB_GETBUTTON,i,(LPARAM)(&BButton));
ReadProcessMemory(hProcess,&BButton,pButton,sizeof(TBBUTTON),&n);
if (pButton->iString != 0xffffffff)
{
try
{
ReadProcessMemory(hProcess,(void *)pButton->iString,name,255,&n);
}
catch(...)
{
}
strInfo.Format("%d : %s\n",i+1,CString(name));
TRACE(strInfo);
qDebug()<<"strInfo = "<<strInfo<<endl;
}
try
{
whd=0;
ReadProcessMemory(hProcess,(void *)pButton->dwData,&whd,4,&n);
}
catch(...)
{
}
proid=NULL;
GetWindowThreadProcessId((HWND)whd,&proid);
if(proid==NULL)
::SendMessage(hNotify1_0,TB_DELETEBUTTON,i,0);
}
delete pButton;
return true;
}
注:上述代码在XP中是可以用的,已经测试,但是,在win7中需要把加粗部分换成下面的代码:
//获取托盘溢出区域窗口句柄
HWND hStatus = ::FindWindow(_T("NotifyIconOverflowWindow"), NULL);
if (hStatus==NULL)
{
qDebug()<<"Get Shell_TrayWnd error!\n";
return false;
}
HWND hNotify1_0 = ::FindWindowEx(hStatus, NULL, _T("ToolbarWindow32"), NULL);
if (hNotify1_0==NULL)
{
qDebug()<<"Get TrayNotifyWnd error!\n";
return false;
}
但是,有时误清除,会把其他的没有结束的进程的图标也关掉。还有待解决。。。
